• A small air gap must be present between cylinder block and

sealing flange after tightening hexagon nut to 35 Nm.

E - Checking installation position of sender wheel on crankshaft:
– Screw hexagon nut -E- to end of threaded spindle.
– Remove bolts -A- from cylinder block.
– Unscrew knurled screws -B- from sealing flange.
– Detach assembly tool -T10134- .
– Detach sealing lip support ring.

– Apply depth gauge -VAS 6082- to crankshaft flange.

– Measure distance between crankshaft flange -A- and sender

wheel -B-.

• Specification: Distance -a- = 0.5 mm.
– Press sender wheel in further if distance -a- is too small

⇒ page 68

– If reading matches specification, continue with assembly
